Abstract

A modular truck body comprises a pair of upstanding side modules each having an L-shaped cross section, a bottom module having its outer edges secured to inner edges of the side modules and an upstanding front module secured between the side modules and having its lower edge secured to the bottom module. The modules are aligned and pre-assembled at a manufacturing plant and then disassembled for shipping purposes. At a customer'"'"'s job site or the like the modules are re-assembled and secured together for installation on the frame of a truck.

Claims

1. A method for making a truck body comprising the steps of

prefabricating a plurality of individual truck body modules,

pre-assembling said modules together and retaining them in pre-aligned relationship relative to each other,

securing combined alignment and releasable fastening means adjacent to edges of each respective pair of said modules,

releasably attaching each respective pair of modules together by said combined alignment and releasable fastening means to form a truck body,

releasing all of said fastening means to disassemble said truck body into said modules,

shipping said modules to a remote location,

re-assembling said modules together into said pre-aligned relationship,

again attaching each respective pair of modules together by said combined alignment and releasable fastening means to re-form said truck body, and

welding said modules together to form a structurally integrated truck body.

2. The method of claim 1 further comprising the step of mounting said integrated truck body on a frame of a vehicle subsequent to said welding step.

3. The method of claim 1 further comprising the step of tack welding said modules together prior to said securing step and subsequent to said pre-assembling step.

4. The method of claim 1 wherein said pre-assembling step comprises the step of inverting said modules.

5. The method of claim 1 further comprising the step of rigidifying said truck body by connecting a plurality of tie rods between said side modules subsequent to said shipping step.

6. The method of claim 1 further comprising the step of securing a canopy module on a forward end of said integrated truck body subsequent to said shipping step.
